Abstract:

A laboratory experiment was carried out with insecticide resistance levels of malathion and deltamethrin against different populations of rusty grain beetle during 2017-18. Cryptolestes ferrugenius populations showed 34.66 and 16.66 folds resistant at LC50 level to malathion (from Machilipatnam and Bapatla, respectively) in comparison to laboratory susceptible Rajahmundry population. Bapatla populations showed 1.75 folds of resistance to deltamethrin and remaining Machilipatnam population has recorded 21.35 folds of resistance to deltamethrin at LC50 level when compared with the succeptible Rajahmundry population at 72 hours after treatment. Machilipatnam population of C. ferrugineus was 4.14 and 9.89 folds resistant at LC99.9 level to malathion and deltamethrin, respectively in comparison with susceptible Rajahmundry population. Similarly, Bapatla population of C. ferrugineus was 1.92 and 2.57 folds resistant at LC99.9 level to malathion and deltamethrin, respectively.
